172 MEMOIRS of the 
a little thin white Icum, that like greafe began to appear on the 
furface, he found to be a number of exceeding fmall Avimakul^ 
of different fhapes and iizes, much like thole produced by keep- 
ing barley in water. 
At the lame time he looked on a fmall drop of the green fur- 
face of iiume puddle-watery this he found to be altogether com- 
pofcd of animals of fevcral fhapes and magnitudes, but the moft 
remarkable were thole, which he found gave the water that green 
colour, and were oval creatures, whole middle part were of a 
grafs-green, but each end was clear and tranlparentj they would 
contract and dilate themfelves, tumble over and over ieveral 
times, and then /hoot away likefilli- their head was at their 
broadeft end, for they Ibll moved that way ; they were very nu- 
merous, but yet fo large, that he could diftinguifh them very 
plainly with a glafs that did not magnify very much • amongft 
thele were interfperled many other fmaller and tranlparent ani- 
mals, like thole mentioned juft now, as found in the whitifli Icum,* 
that was in lome rain water, which had fiood a while uncovered. 
He found another fort of creatures in the water, lome of which 
he had kept in a window, in an open glafs ^ they were as large 
as three of the other with the green border about their middles, 
but thole were perfectly clear and colourlels. Then alio examin- 
ing more accur itely the belts or girdles of green, that were about 
the abovementioned animals, he found them to be compofed of 
globules, lb like the rows or Ipawn of fifli, that he could not 
but imagine, they fcrved for the lame ule in thele little animals j 
for in two days, the number of the old ones, with the green gir- 
dles, decreafed more and more, and at laft he could not lee one 
of them lb encompaf[ed, but they were all clear and colourlefs 
from end to end. In a very fmall drop of puddle-water, which 
was blueifli, or rather of a changeable colour between blue and 
led, he lound prodigious numbers of animals, and of various 
magnitudes j but he found amongft them none with thole girdles 
abovementioned, either of green or any other colour. He then 
alio examined the furface of lome other puddle-water, that 
looked a little greenilh , and this he found ftocked with infinite 
numbers of animals 3 amongft thele, there were many of a 
greenifli colour, but they all moved about with fuch iWiftnels, 
and were lb near each other, that he could not diftinguifl-i, whe- 
ther the green colour were all over their bodies, or whether it 
were on':y round their middle in girdles, as before^ but from the 
roundnels of their figure, and their fmallnels he judged that they 
chiefly conliRed of the young animated fpawn of tde abovemen-
